Unfortunately, I'm currently quite busy. I've sent a report to cyg...@cygwin.com: http://cygwin.com/ml/cygwin/2010-08/msg00745.html > Date arithmetic is pretty esoteric, after all. > What is one month after 31 January, for example? yes, sometimes it's not too important to care about tomorrow ... but sometimes it is ;-) > I'm becoming more inclined to say that GNU date > shouldn't be doing date arithmetic at all. I think it should - the point is that the base for such date arithmetic must be valid. And since 1991-04-14 is a valid date in the OPs timezone, date should IMO return the 15th for "1991-04-14 +1 day" - as Alan wrote. Have a nice day, Berny
